Fire engines have flashing lights for a very important reason!
1. To Get Attention: When a fire engine is driving to a fire or an emergency, it needs to let everyone know that it’s there. The flashing lights help people see the fire engine, even if it's day or night.
2. To Clear the Way: When people see the flashing lights, they know to move to the side of the road. This is very important because fire engines need to get to emergencies quickly to help people.
3. To Show Urgency: Flashing lights mean that something important is happening. It tells everyone, ‘Look! There's a fire truck on its way to help!’
So, those bright flashing lights are like a superhero's signal to help keep everyone safe!
